一种圆形截面的钢丝拉拔前预处理工艺A pretreatment process for steel wire with round cross section before drawing 技术领域Technical field
本发明涉及钢帘线生产技术领域，特别涉及一种用于生产钢帘线的截面为圆形的钢丝拉拔前表面预处理工艺。The invention relates to the technical field of steel cord production, in particular to a pretreatment process for the surface of a steel wire drawing front for drawing steel cords with a circular cross section.
背景技术Background technique
在市场竞争压力下，降本增效是各个企业在市场中谋求发展的必要措施，有限资源的节约使用被制造业提上日程。因此，作为轮胎骨架材料的钢帘线、胎圈钢丝及其它金属制品企业不断接受着性能、成本与能源节约的挑战，加之世界各地越来越重视节能减排，高性能低能耗轮胎的发展越来越快，轮胎对钢丝帘线和胎圈钢丝的要求以及相关行业对金属制品的要求越来越高。因此生产低成本、低能耗、排污少、环境污染少的产品是未来各个行业发展的趋势。Under the pressure of market competition, cost reduction and efficiency increase are necessary measures for enterprises to seek development in the market, and the use of limited resources is put on the agenda by the manufacturing industry. Therefore, steel cords, bead wires and other metal products companies that are used as tire frame materials continue to accept the challenges of performance, cost and energy saving. In addition to the increasing emphasis on energy saving and emission reduction around the world, the development of high-performance low-energy tires Faster and faster, the tires have higher and higher requirements for steel cords and bead wires and related industries for metal products. Therefore, the production of products with low cost, low energy consumption, less pollution and less environmental pollution is the development trend of various industries in the future.
钢丝的拉拔存在于线材生产的各个领域，目前子午线轮胎用骨架材料钢帘线钢丝、胎圈钢丝均通过原材料盘条的一次或多次拉拔得到想要的线径钢丝；原材料盘条表面有大量的硬质磷状表皮和浮锈，为保证钢丝的顺利拉拔，盘条在进入拉拔机拉拔前需要对钢丝表面进行处理，而大部分盘条表面处理均离不开酸洗工艺。The drawing of steel wire exists in various fields of wire production. At present, the steel cord wire and bead wire of the radial tire skeleton material are drawn through the raw material wire rod one or more times to obtain the desired wire diameter; the surface of the raw material wire rod There are a lot of hard phosphorous skin and rust. To ensure the smooth drawing of the steel wire, the wire rod needs to be treated before entering the drawing machine. Most of the wire rod surface treatment is inseparable from pickling Craftsmanship.
现有常规原材料盘条线径在5.0mm～7.0mm之间，目前盘条在拉拔前采用的常规表面预处理工艺，是在盘条机械剥壳后先经过高压水冲洗，然后进行电解酸洗，再进行至少三道串联水洗工序；为保证电解酸洗溶液稳定，每天需有专人对溶液进行维护；为保证各工序槽体溶液不交叉污染，生产时电解酸洗前后水洗必须长期打开，并保持一定的溢流量；废气、废酸的处理需建设专门的处理***，并每天有专人对废气、废酸添加药物进行处理；一旦处理设备出现故障问题，生产现场经常会有一些废气溢出，对现场环境造成较大影响，导致现场设备加快腐蚀，同时对现场人员的身体健康造成一定伤害。The wire diameter of the existing conventional raw material wire rods is between 5.0mm and 7.0mm. At present, the conventional surface pretreatment process used for wire rods before drawing is to wash the wire rods after mechanical peeling and then wash with high-pressure water and then perform electrolytic acid Wash, and then perform at least three series of water washing processes; in order to ensure the stability of the electrolytic pickling solution, a dedicated person is required to maintain the solution every day; to ensure that the tank solution in each process does not cross-contaminate, the washing before and after electrolytic pickling during production must be turned on for a long time. And maintain a certain overflow rate; the treatment of waste gas and waste acid requires the construction of a special treatment system, and there are special people to treat the waste gas and waste acid added drugs every day; once the treatment equipment fails, there will often be some waste gas overflow at the production site, It has a greater impact on the on-site environment, leading to accelerated corrosion of on-site equipment and at the same time causing certain damage to the physical health of on-site personnel.
总体来讲，现有的钢丝拉拔前常规表面预处理工艺存在如下缺点：In general, the existing conventional surface pretreatment process before wire drawing has the following disadvantages:
一、现有的电解酸洗耗电、耗酸，同时为保证酸洗浓度的稳定，需要每天有专人结溶液进行添加维护，钢丝生产成本较高；1. The current electrolytic pickling consumes power and acid. At the same time, in order to ensure the stability of the pickling concentration, a special person needs to add solution for maintenance every day, and the production cost of steel wire is relatively high;
二、电解酸洗后钢丝表面有大量残留酸，为防止槽体间交叉污染，需要大量水对钢丝表面进行冲洗，增加了生产成本；2. After electrolytic pickling, there is a large amount of residual acid on the surface of the steel wire. To prevent cross-contamination between the tanks, a large amount of water is required to wash the surface of the steel wire, which increases the production cost;
三、废气、废酸的处理需要建设专门的处理***，同时投入较大处理成本，给企业带来了较大负担；3. The treatment of waste gas and waste acid requires the construction of a special treatment system, and at the same time, a large treatment cost is invested, which brings a large burden to the enterprise;
四、电解酸洗工艺废气处理不当或设备故障对现场环境造成较大影响，导致现场设备加快腐蚀，同时对现场人员的身体健康造成较大伤害；4. Improper exhaust gas treatment or equipment failure of the electrolytic pickling process has a greater impact on the on-site environment, resulting in accelerated corrosion of on-site equipment and greater damage to the health of on-site personnel;
五、电解酸洗处理后的钢丝表面非常光滑，后续拉拔时带润滑粉量不足易导致钢丝拉拔不畅，影响拉丝的成品率，废料较多造成生产成本上升。Fifth, the surface of the steel wire after electrolytic pickling treatment is very smooth. Insufficient amount of lubricating powder during subsequent drawing may easily lead to poor drawing of the steel wire, which affects the yield rate of the wire drawing and increases the production cost due to more waste.
